LONDON: Hollywood actor Colin Farrell has no idea why he has very little recollection of his former self. The star reckons he has lost 10 years worth of memories thanks to a hedonistic existence of drink, drugs and excess partying, reports thesun.co.uk. And only now the Irish actor is clean after he realised just how much of his life he has missed out on. “There are probably more moments in my life that I can’t remember than when I can. The last ten years are pretty sketchy. But as soon as I gave up certain things and put them to one side in my life, then everything became a lot clearer,” Farrell said.
